Acetylcholine binds to sarcolemma; sarcolemma then T-tubules depolarize; Ca++ released from terminal cisternae travels along SR, is release into sarcoplasm, then binds to troponin to unblock tropomyosin binding sites allowing cross-bridge formation (i.e., myosin heads bind to actin).

During the latent period of a chemical reaction, molecules are rearranging and transitioning into activated states to reach the transition state, which is a high-energy state that leads to products formation. Chemical bonds may be breaking and forming during this time, but overall there is no net change in the concentrations of reactants or products in the system.

What is the relationship between energy and phase changes?
During phase changes, energy is either absorbed or released in the form of heat. This energy is used to break or form intermolecular forces between particles. As a result, temperature remains constant during the phase change until all the substance has transitioned to the new phase.
List two changes of state of water that cause latent heat to be released?
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released.
What happens when a gas reaches a cold surface and it changes into a liquid?
When a gas comes into contact with a cold surface and loses heat energy, its molecules slow down and move closer together. This causes the gas to condense and change into a liquid state.
Explain why the temperature of Wax remains constant during solidification?
The temperature of wax remains constant during solidification because the heat energy released as the wax cools down is used to break the intermolecular bonds in the solidifying wax, rather than increase its temperature. This energy is known as the latent heat of fusion and allows the wax molecules to form a solid structure without a change in temperature.
When water vapor changes to liquid water it does what?
When water vapor changes to liquid water, it condenses. This process releases latent heat energy into the surroundings.
Is a typhoon a chemical change?
No, a typhoon is a physical structure energized by the latent heat of phase changes involving water.
Does heat energy add during condensation?
During condensation, heat energy is released as water vapor changes to liquid water. This is known as the latent heat of condensation.
What is the heat that is released when water condenses and changes to liquid form?
The latent heat of vaporisation.
Is energy released or absorbed when water changes state from a solid to a liquid to a gas?
Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
The energy that gas changes to liquid?
The latent heat of condensation.
Does Jimmy Swaggart suffer from Tourette syndrome?
Probably not. A nervous twitch could be a latent fear of the imminent rapture occurring.
What is latent energy in a fuel?
Latent energy in a fuel refers to the energy released during the combustion process of the fuel. This energy is stored within the chemical bonds of the fuel and is released in the form of heat when the fuel is burned. It is a crucial factor in determining the energy content and efficiency of a fuel.
What are two changes of state for water that cause latent heat to be released?
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released. These changes of state involve the release of latent heat because energy is being released as the water molecules transition to a lower energy state.
Why doesn't the thermometer measure latent heat?
A thermometer measures temperature by detecting the average kinetic energy of the particles in a substance, rather than the energy involved in phase changes, such as latent heat. Latent heat is the energy absorbed or released during a phase change, like melting or boiling, and does not directly affect the average kinetic energy of the particles that the thermometer detects.
Which chemical treatment produces a white-appearing latent print?
Ninhydrin treatment can produce a white-appearing latent print on porous surfaces by reacting with amino acids present in the print residue.
Which term refers to the energy that is stored or released during a change of statement of water?
The term is "latent heat." It represents the energy absorbed or released by a substance during a phase change, such as when water changes from a liquid to a solid or a gas.
What is the relationship between energy and phase changes?
During phase changes, energy is either absorbed or released in the form of heat. This energy is used to break or form intermolecular forces between particles. As a result, temperature remains constant during the phase change until all the substance has transitioned to the new phase.
